A high-frequency signal occurring at epileptic seizure onset is investigated using time-frequency methods. This signal is extracted from the background activity by repeated forward and inverse Gabor transformations. The generation sites of this signal are determined by displaying the average signal power values with a 3-D anatomical image obtained from MRI scans.
